Title: Production of seat pad
Inventor: MAEDA MINORU
IPC: B29C39/10
Filed: 1985-07-08
Abstract: PURPOSE:To produce a pad of good quality without forming any voids by forming a cured layer integrated with the pad, by compressing a porous open- cell foam and allowing a synthetic expanded resin to penetrate into the inner layer thereof by a sucking force caused by restoration. CONSTITUTION:A foam 4 is placed on the inner side of the lower plate 32 of a pressing plate 34 by supporting it with a support pin 35. an expanded resin 5 is put into a mold 3. The mold 3 is fixed by clamping it, and the foam 4 is put between a pressing plate 33 and the pressing plate 34 and compressed. The plates 33, 34 are detached from each other to thereby release the foam 4 from pressing. The foam 4 is expanded so as to be restored to the original plate thickness. The expanded resin 5 during the course of expansion is sucked and allowed to penetrate into the inner layer of the foam to form a relatively thick cured resin layer. Since the foam is left on the support 35, the expanded resin 5 flows into the space between the foam 4 and the pressing plate 34 so that the foam 4 is introduced into the inner layer of the pad 1, whereby the foam and the pad can be integrally molded.

CONSTITUTION:The inclination preventing means 12 and 13 for preventing the inclination of the original platen 2 when the center of the gravity of the original platen 2 is out of the device main body because of the movement of the original platen 2 are disposed on the end part side of the device main body. In such a case, the means 12 and 13 are L-shaped angle members which guide the side end of the original platen 2 in a moving direction and which prevent the inclination, and a tapered surface is formed on the surface of the angle member opposed to the original platen 2 in a direction in which the inclination is prevented. On the back end part side of the original platen 2, the tapered surface is formed in the direction in which the inclination is prevented by engaging with the angle member. Therefore, the original platen 2 is smoothly moved and the floating of the original platen 2 is prevented, so that the out-of-focus is prevented, and further the device is miniaturized.

Title: Detecting method for variation of tape running and tape running control device
Inventor: SAITO HIROSHI
IPC: G11B15/46
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of misreading of a target tape position of top/end of a tape by detecting variation caused on a tape being running at high speed based on the number of rotations of a supply side reel when a tape is wound by rotating a winding side reel at high speed. SOLUTION: When full-forward(FF)/rewind(REW) is started, it is judged whether an adjacent position including a decreasing speed start point position is a detecting section or not from winding quantity of a tape 11 being previously known and the number of rotations of a supply reel 19 or a take-up reel 20. When it is a detecting section, the number of rotations of supply side reels are compared, frequency components of eight FG signals in a detection period of the previous time are compared with frequency components of eight FG signals in a detection period of this time, difference between frequencies is calculated to obtain difference between the number of rotations. When difference is the prescribed number of rotations or more, increment is performed in a counter 35, it is considered that variation is caused in high speed running of a tape, decreasing speed control processing is advanced by performing the prescribed processing.

IPC: H05K1/03
Filed: 1988-06-17
Abstract: PURPOSE:To reduce a warpage change and to enhance punching processability by compounding polyalkylene glycol with an N-methylol compound to perform the treatment of paper and containing polyalkylen glycol in much quantities on a metal foil containing side as compared with a metal foil non-containing side. CONSTITUTION:In a process for manufacturing a single surface metal foil clad laminated sheet containing the impregnation of a base material with a low pressure molding grade curable resin, the lamination of the impregnated base material and curing, polyalkylene glycol is compounded with the N-methylol compound used in the treatment of a paper base material to plasticize the N-methylol compound and the content of polyalkylene glycol across the center surface bisecting a required number of the paper base materials constituting the laminated sheet in the thickness direction of the laminated sheet is made much on the metal foil containing side as compared with a metal foil non-containing side. When much polyalkylene glycol is contained on the metal foil side, a plus tendency is obtained and, since the curing shrinkage quantity of the adhesive of the metal foil exceeds that of the single surface metal foil clad laminated sheet, said sheet easily becomes minus warpage. Then, it is pref. that the distribution of polyalkylene glycol in the laminated sheet is inclined toward the metal foil.

Title: Inkjet recording apparatus
Inventor: YAMASHITA TOMIO
IPC: B41J29/38
Filed: 1991-05-24
Abstract: PURPOSE:To positively prevent cloggings in a simple structure when such an abnormal state as an erroneous manipulation, an interruption of power supply, etc., is brought about, by using a pressing plate of a to-be-recorded material against a platen also as a lid of an ink discharge port. CONSTITUTION:A driving magnet 2 is activated when the power switch is turned on. At the recording time, a to-be-recorded material 4 is transferred in tight contact with the peripheral surface of a platen roller 3 by an end of a pressing plate 1, with a suitable gap secured from the front end face of a recording head 7. When the power source is shut because of an abnormal condition, for example, the user's inadvertent manipulation or interruption of power supply, the magnetic attractive force of the driving magnet 2 is lost, and the pressing plate 1 is moved upward by the restoring force of a spring 13. As a result, a buffer pad 12 of elastic rubber-like material is automatically brought in tight contact with a protecting frame 8 of the recording head 7, thus capping the face where a discharge port is formed. Accordingly, it is not necessary to detect the state of the power switch by cutting the switch secondarily, or process the recording head specially. The recording head is capped in a considerably simple arrangement, thereby preventing cloggings of the discharge port reliably.

Abstract: PURPOSE: To hold a PU arm moved to a record position at a correct position, by servo-controlling a PU driving motor by an output of a position detecting means of the PU arm.  
     CONSTITUTION: A position detecting means 10 generates an output signal which is varied in accordance with a turning position of a horizontal turning shaft 11 for supporting a PU arm 12. That is to say, in accordance with size of a record, a sensor plate 13 having three slits is provided. When the turning shaft 11 is turned by a driving motor 70, the output of the detecting means 10 is amplified 20, and after that, is detected by a level detecting circuit 30. A level of this detecting signal is compared with a prescribed level by a motor driving circuit 60 in accordance with the record size information from an operation part 50. In accordance with its result, the driving circuit 60 servo-controls the driving motor 70. In this way, the PU arm which has moved up to the record position is held at a correct position without shifting its position.

Title: Regulation of silicon nitride powder
Inventor: ADACHI JINICHI
IPC: C04B35/58
Filed: 1987-06-18
Abstract: PURPOSE:To uniformly incorporate specified quantities of oxygen into silicon nitride powder by grinding silicon nitride raw powder at specified temperatures in the form of an aqueous slurry to increase the oxygen content in the powder. CONSTITUTION:Silicon nitride raw powder is ground in the form of an aqueous slurry while keeping the slurry at 35-100 deg.C to increase the oxygen content in the powder. Through the above process, the oxidation on the powder surface can be more enhanced by wet grinding of the raw powder while keeping the slurry temperature at 35-100 deg.C than by conventional grinding in water at <=35 deg.C, thus specified quantities of oxygen can uniformly be incorporated into the powder by regulation of both slurry temperature and grinding time. The silicon nitride sintered substances obtained using the resultant silicon nitride powder regulated by the above process, are excellent in mechanical strength, wear resistance, oxidation resistance, etc.; therefore, being useful for mechanical parts such as bearings, automobile parts such as turbochargers, etc.
